Although the prognostic value of perfusion MR imaging in various gliomas has been investigated, that high-grade astrocytomas alone not fully evaluated. The purpose this study was to evaluate retrospectively whether tumor maximum relative cerebral blood volume (rCBV) on pretreatment is patients with astrocytoma.Between January 1999 and December 2002, 49 (30 men, 19 women; age range, 23-76 years) supratentorial astrocytoma underwent before inception treatment. patient age, sex, symptom...
<h3>BACKGROUND AND PURPOSE:</h3> The usefulness of contrast-enhanced 3D T2-FLAIR MR imaging for the evaluation leptomeningeal diseases has not been systematically investigated. purpose this study was to assess value added by and MPRAGE sequences conventional postcontrast T1-weighted images in diseases. We also undertook vitro studies attempts understand consequences our patient study. <h3>MATERIALS METHODS:</h3> Twelve patients with confirmed underwent T1-weighted, MPRAGE, at 3T. Two...
<h3>BACKGROUND AND PURPOSE:</h3> Four-dimensional contrast-enhanced MR angiography (4D-CE-MRA) at 3T may replace digital subtraction (DSA) for certain diagnostic purposes in patients with intracranial dural arteriovenous fistula (DAVF). The aim of this study was to test the hypothesis that 4D-CE-MRA enables same characterization DAVFs as DSA. <h3>MATERIALS METHODS:</h3> population consisted 18 consecutive (11 women, 7 men; age range, 35–82 years; mean age, 64.8 years). They underwent and...
QUASAR is a particular application of the ASL method and facilitates user-independent quantification brain perfusion. The purpose this study was to assess intermodality agreement TBF measurements obtained with DSC MR imaging inter- intraobserver reproducibility glioma acquired by at 3T.Two observers independently measured in 24 patients histologically proved glioma. were performed on 3T scanners. placed 5 regions interest solid tumor rCBF maps derived from images 1 region contralateral...
<b>BACKGROUND AND PURPOSE:</b> Differentiation between paraclinoid and cavernous sinus aneurysms of the internal carotid artery (ICA) is critical when considering treatment options. The purpose this study was to determine whether contrast-enhanced (CE) 3D constructive interference in steady state (CISS) MR imaging useful differentiate aneurysms. <b>MATERIALS METHODS:</b> This included 11 10 consecutive female patients, ranging from 52 66 years age. All were adjacent anterior clinoid process....
The pathological significance of advanced glycation end product (AGE)-modified proteins deposited in several lesions is generally accounted for by their cellular interaction via the AGE receptors and subsequent acceleration inflammatory process. In this study, we focused on two receptors-specifically, role SR-A pathogenesis diabetic nephropathy CD36 AGE-induced downregulation leptin adipocytes. terms SR-A, wild-type mice exhibited increased urinary albumin excretion, glomerular hypertrophy,...
Purpose: Differences in acute adverse reactions to different gadolinium (Gd)-based contrast agents have not been thoroughly evaluated. We investigated the relationships among incidence and severity of reactions, backgrounds patients, 4 types Gd-based (gadopentetate dimeglumine, gadoteridol, gadoterate meglumine, gadoxetate disodium).Materials Methods: retrospectively reviewed radiological records 10,595 consecutive patients (4,343 female; 6,252 male; mean age, 63.8 ± 14.0 years) who...
The purpose of this research is to develop a laboratory-based near-infrared (NIR) hyperspectral imaging system measure the two-dimensional distribution nitrate concentrations in vegetable leaf as tool for precisely analysing metabolism. Komatsuna leaves were analyzed by reflectance range from 607 967 nm with resolution 9 nm. was standardized reference plate and converted relative reflectance. An algorithm select effective wavelength predict concentration developed conjunction partial least...
Reliable information on weed abundance and distribution within fields is essential for management in agricultural systems. Such necessary to adopt localized variable rates of herbicide spraying, thus reducing chemical waste, crop damage, environmental pollution. This paper examined the potential airborne multispectral imagery discriminate map infestations an experimental citrus orchard Japan. Using digital sensor, was acquired over study site 10 April 2003. The obtained reflectance analyzed...
<h3>BACKGROUND AND PURPOSE:</h3> The vascular supply of extra-axial brain tumors provided by the external carotid artery has not been studied with RPI. purpose this work was to determine whether RPI assessment is feasible and provides information on hypervascular tumors. <h3>MATERIALS METHODS:</h3> Conventional ASL studies were performed at 3T in 8 consecutive patients meningioma. On basis MRA results, we placing a selective labeling slab over artery. Five underwent DSA before surgery. Two...
Hyperspectral imagery has become increasingly available in recent years and this necessitated the evaluation of its potential for crop monitoring precision agriculture applications. The using airborne hyperspectral to develop yield prediction models citrus fruits was examined paper. images 72 visible near-infrared (NIR) wavelengths (407–898 nm) were acquired over a orchard Japan by an Airborne Imaging Spectrometer Applications (AISA) Eagle system. canopy spectral features individual trees...
